Just found the site doing some resarch about my '03 grand so i figured i would give you guys a shot. The problem is when i hit 70 on the highway i get a pretty bad vibration but i dont feel it in the steering wheel i can feel it in my a$$. also when i turn the steering wheel to the left like when im changing lanes there is a pretty bad noise. any ideas as to what could be causing this.
hmmm...sounds like a drivetrain vibration to me. Take a look at the diveshafts and see if there is any play or leaking fluids from them.

I would check your rear DS ujoints first for play.. that's free to check right... :-P If there's no play I'd get your tires balanced again. You could take your rear tires and put them in the front and see if you feel the vibrations in the steering will... if you do then you know its one of those two wheels/tires.
what transfer case do you have? you implied you replaced tires only on the front? what about the rears? you should always replace tires on the front and the rear on 4wd jeeps. especially full time 4wd units like quadradrive
after replacing the engine in my 99 wj id had enough. now its a toyota truck
